VPFHT-12.5C-4910 12.5 mm Dia. Mounted Laser Line Filter; t=3.5mm 491nm

OptoSigma's VPFHT-12.5C-4910 is a laser-line filter with a circular base shape and a diameter of 12.5 mm. This filter is designed to operate at a wavelength of 491 nm, making it suitable for a range of applications that require precise wavelength control.

The filter is constructed with a material identified as UVFS MAL-1965, and it has a thickness of 3.5 mm. This combination of material and thickness ensures the filter's durability and efficiency.

The VPFHT-12.5C-4910 features a coating on both the front and back surfaces, specifically an opt VPFHT-4910 coating. This coating is designed to optimize the filter's performance, enhancing its ability to block unwanted wavelengths and transmit the desired 491 nm light.

The filter's shape is classified as a thin lens, suggesting that it may have some light-focusing capabilities in addition to its wavelength-filtering function. This could make it a versatile option for users who need a component that can both filter and focus light.
